OPTION TO COMMIT STOCK FOR A CUSTOMER

Dear All ,

is there an option in the system , where we can block certain number of quantities for certain items , for particular customer ?

let's say , we have 500 KG on hand as well as available for item code X001.

out of 500 KG , commit 200 KG for one customer .

is that possible in the system ? or is there any work around can be done for this ?

kindly advise

thank you in advance .
